on I'm new here and I have a question for everyone. My 06 350z has black spyder headlights, but the high beam on the passager side won't light when I turn high beams on. The other side works perfectly, low beam turns off and high comes on, but the passager light stays on low beam, and won't switch to high. I've checked all the fuses and relays on the car, and everything is fine. I don't think it's the bulb because it would still try to switch to the high beam but it wouldn't light. The manufacturer isn't much help so I was hoping someone here could help me. Thanks

 

Crap lights....did you put them or were they on the car when you bought it?

 

Swap bulbs and see if it lights on the other side. Easiest way to determine it's not a dead bulb.

Also, sh!tty lights will give sh!tty results.

 

I put them in. The oem ones had lenses that were so fogged and uv damaged that it was affecting light output. I found these lights cheap and got them to use just until I get the funds to have the oem lights redone. I'm just trying to fix these so I can pass emissions, I don't expect to be keeping them very long.

 

OK, here's the real question, are these "Spyder" things actually designed for R&R of '06+ lights because if they are, the problem is likely in the shutter/lens assembly as Bi-Xenon bulbs do NOT brighten, the shutter just opens all the way to allow for a high beam with full intensity of the bulb to shine through.

 

I don't believe they have a shutter like the OEM BiXenon's, they have two separate lenses/bulbs, like the older OEM lights.

 

Exactly my point. Swapping out 06+ lamps for "cool JDM" stuff.... SMH.

 

I'm having the same issue with my car. Did you find a solution or a fix. All headlight fuses are good. Passenger side high beam won't come on. Low beam won't turn off?

 

Doubt you're gonna get a response from someone who only has two posts on this forum almost exactly five years ago.

Put stock headlights in. Replace bulbs. Problem solved.
